2023-03-17 09:15:36

The particle counter was developed by microscope, and it has undergone the processes of microscope, settling tube, sedimentation instrument, centrifugal sedimentation instrument, particle counter, laser air particle counter, PCS nano laser air particle counter. The laser air particle counter test is fast and dynamic. Wide-ranging, unaffected by human factors and other advantages, and become an advantage product in many industries. Can be widely used in various provinces and municipal drug inspection institutes, blood centers, epidemic prevention stations, disease control centers, quality supervision institutes, electronics industry, pharmaceutical workshops, semiconductor, optical or precision machining, plastics, painting, hospitals, environmental protection, inspection Such as production companies and scientific research departments. The relevant requirements when using the dust particle counter are as follows:

1. It is forbidden to extract gases containing oily and corrosive substances, and do not measure mixed gases (such as hydrogen and oxygen) that may react. These gases may also explode in the counter. If these gases are to be contacted, contact the manufacturer to obtain more information and then operate.

2. When handling, it should be handled lightly and with less vibration and impact. Especially for desktop particle counters, be more careful to avoid damage to internal components;

3. No high pressure decompression equipment (such as high pressure diffuser) should not sample compressed air. All counters are designed to operate at one atmosphere. The working position and sampling port of the instrument should be in the same air pressure and the same temperature and humidity environment to ensure the normal operation of the instrument;

4. When connecting an external printer or connecting an external temperature and humidity sensor, you need to turn off the counter first; when performing the printing operation, the printer must have printing paper, otherwise it will damage the print head;

5. When the inlet pipe is covered or blocked, do not start the dust particle counter;

6. The particle counter is mainly used to test the clean environment of the purification workshop. When the measured material has loose particle material, dust source and spray, it must be kept at least twelve inches away from the inlet pipe. In order to avoid contamination of the sensor and pipeline with the above particles and liquids;

7. When sampling, avoid sampling the gas contaminated by the gas discharged from the counter itself;

8, should be used in a clean environment to prevent damage to the laser sensor;

9. An aqueous solution or other liquid cannot enter the sensor from the inlet tube.

Conference Interactive Whiteboard

As a conference all-in-one machine, conference Interactive Whiteboard, microphones and conference software. The small size contains great momentum, providing high-quality pictures and sound effects for team video conferences.
In terms of camera hardware configuration, the electronic Interactive Digital Board uses a 12 million pixel camera and supports a wide viewing angle of 120 degree. It can be used in small and medium-sized office spaces and can incorporate more team members into the video conference scene. 4K high-definition resolution can provide high-quality video images, adding points to the corporate image.
In terms of sound experience, interactive digital board has built-in 6 array microphones to bring high-fidelity sound quality, and conference interactive smart board can achieve up to 8 meters of remote sound pickup, and can perform accurate sound in every corner of the meeting room. At the same time, in the remote meeting mode, the tablet will locate the sound source so that the speaker will not be able to display the picture, automatically gain the voice, eliminate echo and noise, even if the speaker is far away, the audience can still hear it.
